仮桟橋を構築する(図1参照)。Next, a method of constructing the temporary pier will be described. First, the support 2 having the ground plate 4 and the lower girder material 3 are assembled, and the support 2 is provided with the pressing means 7, the driving device 6 and the auger 5 built therein to produce the base 1. The base 1 is manufactured in advance in a factory, and the assembled base 1 is transported to the construction site. Next, at the construction site, lift the transported base 1 with a crane or the like,
Install on the bottom of the water at regular intervals. During this installation,
The ground pressure is increased by contacting the ground plate 4 with the ground at the bottom of the water. After that, the driving device 6 is driven to rotate the auger 5, and the pressing means 7 is driven to extend the rod 8. As a result, the auger 5 bites into the ground along the coaxial line with the support 2 while rotating, so that supporting force can be obtained from the ground. Therefore, the base 1 is more stable.
Then, the upper girder material 9 is provided between the lower girder materials 3 at the upper ends of the adjacent bases 1.
And the lining plate 10 is laid on the upper girder material 9 to construct a temporary pier (see FIG. 1).

も適用できる。FIG. 4 shows a height adjusting mechanism of the support column. The support column 2 is constituted by the upper member 21 and the lower member 22 slidably inserted in the lower portion of the upper member 21, and the upper end of the upper member 21 is further constituted. The lower girder material is attached to the part. As a result, the height of the column 2 can be adjusted. Further, if the left and right lower members 22 are configured to be independently expandable and contractible, horizontal adjustment can be easily performed on the sloping ground of each base. Vertical movement of these upper members 21 is carried out by lifting them with a crane or the like. After adjusting the height, fix them with bolts and pins. By making the strut 2 expandable and contractable in this way, the heights of the bases can be made uniform even when the bases are installed on an inclined water bottom, and the height and level of the lining plate can be easily adjusted. You can This height adjusting method can also be applied to the pillars of the triangular base shown in FIG.
